摘要： A method and system for managing the transfer of data into and out of a buffer in a disc drive is disclosed. The operation of the vectored buffer management (VBM) system is administered by a software-based control module. The control module creates and maintains a buffer table by dividing the buffer table into buffer sectors. The buffer sectors are further arranged into buffer segments, or circularly linked lists upon which the buffer table is partitioned. The control module effectuates the transfer by implementing an application module across the buffer table. Once the application module is arbitrarily positioned at an index sector by the control module, data transfer is accomplished when the application module walks through a particular buffer segment identified by the index sector. Specific control of the application module across a buffer segment is administered through host and disc address pointers, which are coupled to host and disc next pointers, respectively.

摘要： Method and apparatus for actively protecting a device from damage due to an impact or other acceleration condition. An active protection system is provided with a sensor which outputs an acceleration signal in relation to an acceleration state of the device. A circuit processes the acceleration signal in relation to a configuration control input indicative of an operational environment in which the device is operated, and a protection mechanism configures the device in relation to the processed acceleration signal. A configuration control module preferably supplies the configuration control input as a user selectable or host input. Preferably, protection mechanism places the device in a protective state to protect against damage due to an imminent impact, such as from a free fall condition. The processing preferably comprises adaptive filtering of the acceleration signal and the application of one or more thresholds to detect said imminent impact.
